I got the soundtrack as soon as it came out and I can honestly say I've listened to it at least once every day since. My favorite tracks have to be 'The Ring Goes South' and 'Concerning Hobbits'. 'The Ring Goes South' is very emotional to me. It's a turning point, because after that, for those 9 people, nothing will ever be the same.
Have any of you listened to the Soundtrack, WHILE reading the books? I did. It's so cool, no matter what part of the story you are reading at any given moment, there is something on that soundtrack that fits with the action on the page.
